Part is embodied by the further advantage of the present invention, target and feature by description below, and part also will be by the present invention
Research and practice and be understood by the person skilled in the art.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the charging method of the lead-acid battery of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description word energy
Enough implement according to this.
Should be appreciated that used herein such as " have ", " comprising " and " including " term do not allot one or many
Other element individual or the existence of a combination thereof or interpolation.
As it is shown in figure 1, the present invention is plumbic acid when providing the charging method of a kind of lead-acid battery, main power source and stand-by power supply different
Battery charges, and comprises the following steps:
Whether step one, the first testing circuit detection main power source are charging to lead-acid battery, when the test results is yes, it is judged that
Whether the terminal voltage of described lead-acid battery is more than or equal to the first predetermined voltage, and this first predetermined voltage determines that main power source or standby
Power supply is the foundation of lead-acid battery charging.When the test results is yes, the first initial value of charging current is set, when lasting
Between be 200～480 seconds charging interval in, the charging current of the first initial value size making size be charging current is by described
Lead-acid battery, charging starting stage electric current is less, so that lead-acid battery progressively adapts to this charging process.Then when lasting
Between be 30～40 minutes charging interval in, control the size of charging current with the speed increase of 2～3 amperes/second, continuing
In time is the discharge time of 60～120 seconds, the size controlling discharge current was successively decreased with the time of 0.01～0.03 ampere/second,
Charging current now is kept 50～90 seconds, the most repeatedly, until described first testing circuit detects described lead-acid battery
Terminal voltage more than or equal to the second predetermined voltage, charging complete.Within the time cycle set, battery recharge and electric discharge
Circulation, can help reduce " memory " effect, this effect can reduce the capacity of battery in time, decrease heating,
The maximum electricity can being filled in battery is caused to increase.When described first testing circuit detects that main power source is not to described plumbic acid
During battery charging, enter step 2.
Step 2, stand-by power supply are the charging of described lead-acid battery, and the second testing circuit judges that the terminal voltage of described lead-acid battery is
No less than described first predetermined voltage, when the test results is yes, set the second initial value of charging current, in the persistent period

State main power source to be connected with described lead-acid battery.By the charged state of the first on-off control main power source Yu lead-acid battery, until complete
Become charging process.
In the charging method of described lead-acid battery, described second testing circuit connects described stand-by power supply by second switch,
Described stand-by power supply is connected with described lead-acid battery.The charged state of stand-by power supply and lead-acid battery is controlled by second switch,
Until the terminal voltage of lead-acid battery is more than or equal to the first predetermined voltage.
In the charging method of described lead-acid battery, also including a governor circuit, described governor circuit is opened with described first simultaneously
Close and second switch connects, to control described main power source and the described stand-by power supply charging interval to described lead-acid battery respectively.
Governor circuit adjusts the duty of whole circuit, to realize the maximization of the utilization of resources, it is ensured that each assembly properly functioning.
In the charging method of described lead-acid battery, described first predetermined voltage is 10V, and described second predetermined voltage is 15V.
The electric current that stand-by power supply provides reaches the first predetermined voltage, and main power source can steadily be charged, and the two cooperates,
Improve charge efficiency.
In the charging method of described lead-acid battery, the first initial value of described charging current is 5 amperes, described charging current
The second initial value be 20 amperes.Main power source charging time electric current initial value more than stand-by power supply charge time initial value be because of
Charging interval for main power source is longer, if current increase is very fast, the infringement to lead-acid battery is bigger；And stand-by power supply needs
Wanting within a short period of time and the terminal voltage of lead-acid battery is pressurized to the first predetermined pressurization, bigger initial charge current shortens fills
The electricity time.
In the charging method of described lead-acid battery, in described step 2, after reaching the charging interval within a cycle, protect
Hold electric current 10 now～20 seconds, then carry out iterative cycles, so that stand-by power supply to be played a protective role.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed utilization,
It can be applied to various applicable the field of the invention completely, for those skilled in the art, is easily achieved
Amendment additionally, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention is not limited to spy
Fixed details and shown here as with describe legend.
